If you were intrigued by those 21-inch e-paper tablets Bridgestone showcased last year, you're sure to be bummed by this news. The company has announced that plans to withdraw from the electronic paper business and expects to bring production to a screeching halt by the end of October. Citing increased competition and rapid declines in material prices for the move, the outfit looks "to put an increased focus on its core businesses." As you may recall, Bridgestone had partnered with Delta Electronics to develop the business-focused AeroBee tablets and it remains to be seen if the latter part of the duo will continue its e-paper exploits with a new mate.
